Becker put a fuse at the back of the radio. Pull the radio, pop out the plastic fuse holder and replace the fuse with a new one, Radio Shack has them. Were you running your tape at the time? Autoreversing the tape puts a load on the system and pops fuses if you don't have a slo-blo version - sometimes them too.
